Abstract
The purpose of this study is to improve interfacial adhesion strength of carbon fiber reinforced hybrid composites by physical and chemical treatment. Ultrasonic irradiation was used as physical and chemical treatment relatively. The morphologies of fracture-section and surface of carbon fiber fabric/CNT reinforced hybrid composites were observed by SEM. The morphologies of specimens treated with ultrasonic showed rougher and more compact surfaces than those of untreated specimens. The specimens treated with ultrasonic showed higher impact strength compared with untreated specimens. This result showed ultrasonic irradiation is one of the effective method to improve interfacial adhesion strength between carbon fiber and matrix.
